在Yii 1.1中,此代码适用于默认排序:

$dataProvider = new CActiveDataProvider('article',array(
    'sort'=>array(
        'defaultOrder'=>'id DESC',
    ),
));

如何在Yii2中设置默认排序？

尝试下面的代码,但没有结果:

$dataProvider = new ActiveDataProvider([
    'query' => $query,
    'sort' => ['defaultOrder'=>'topic_order asc']
]);

如何使一个dropdown在yii2使用activeform和模式？由于所有方法都已改变yii2,如何在新的方法中完成？

我安装了最新版本(1.0.0.稳定版)的作曲家,在我的Yii2项目中输入了这个:

php composer.phar update

它给了我这个错误:

[ReflectionException]类Fxp\Composer\AssetPlugin\Repository\NpmRepository不存在

[ErrorException]声明Fxp\Composer\AssetPlugin\Repository\AbstractAssetsRepository :: whatProvides()应与Composer\Repository\ComposerRepository :: whatProvides(Composer\DependencyResolver\Pool $ pool,$ name,$ bypassFilters = false)兼容

有人可以帮我解决这个问题吗？

这是我的composer.json

如何在Yii2中启用干净的URL.我想删除index.php和'？' 来自url参数.需要在Yii2中编辑哪个部分？

我正在通过作曲家更新我的yii2,然后又回到旧的测试版.

这是我作曲家的错误:

我有两个数据库,每个数据库都有相同字段的相同表,但如何在Yii 2.0中同时获取所有两个数据库中的所有记录？

在yii2 gridview中,我有这个代码:

<?php echo GridView::widget([
  'dataProvider' => $dataProvider,
  'filterModel' => $searchModel,
  'columns' => [
    ['class' => 'yii\grid\SerialColumn'],
    [
       'label' => 'bla',
       'format' => 'url',
       'value' => function ($data) {
            return Html::url('site/index');
       },
    ],
    ['class' => 'yii\grid\ActionColumn'],
  ],
]); ?>

在网格视图中,使用url地址生成文本.

/学术界 - 新/高级/管理/网站/指数

网址工作正常,但如何为链接设置文字？

我这样做:

$students = Student::find()->all();
    return $this->render('process', array('students' => $students));

然后在视图中:

foreach($students as $student)
    {
        echo $student->name . ',  ';
        echo $student->getQuizActivitiesCount(); ?> <br /> <?php
    }

我想看看正在执行的SQL查询.学生"有很多"测验活动,查询表现完美,但我需要查看原始SQL.这可能吗？

我想从控制器发送参数到布局(即main.php).但是我无法在main.php中获得参数

我试过了:

控制器代码:

$this->render('index',array('param' => $paramValue));

这就是我试图在布局中得到这个的方式.main.php

1. $this->param (如yii 1)
2. $param

但我无法在布局中获得参数值.谁能告诉我怎么做？

Yii框架中高级应用程序和基本应用程序有什么区别？

他们在安全方面有什么不同吗？
